Abstract

The disclosure relates to a system for separating carbon dioxide from a gas flow, in particular from an air flow. The system comprises at least one first functional unit and at least one second functional unit connected downstream of the first functional unit in the flow direction of a main air flow through the system. It is provided that the first functional unit has a first number of functional modules and the second functional unit has a second number of functional modules, wherein the second number is higher than the first number.

         6 . The system of  claim 1 , wherein a flow distribution chamber is arranged between the first functional unit and the second functional unit in order to divide a gas flow exiting a functional module of the first functional unit among multiple functional modules of the second functional unit. 
     
     
         7 . The system of  claim 1 , wherein a distance between the first functional unit and the second functional unit is at most 2 m. 
     
     
         8 . The system of  claim 1 , wherein the system has a return line with which a dried, carbon dioxide-reduced gas flow is drawn off downstream of the sorption unit and fed back to the pre-conditioner. 
     
     
         9 . The system of  claim 1 , wherein an inlet of a functional unit is formed or arranged perpendicularly to an outlet of the same functional unit. 
     
     
         10 . The system of  claim 1 , wherein a pipeline is provided at the gas flow outlets of the first functional unit, wherein the pipeline has at least two openings for the common discharge of a gas flow of the functional modules directly upstream of the pipeline. 
     
     
         11 . The system of  claim 10 , wherein the first functional unit is a pre-conditioner and the second functional unit is a dryer.

         13 . The system of  claim 12 , wherein the first functional unit is a pre-conditioner, the second functional unit is a dryer, and the third functional unit is a sorption unit. 
     
     
         14 . The system of  claim 1 , wherein the system has a pre-conditioner, a dryer following on from the pre-conditioner in the flow direction of a main air flow through the system, and a sorption unit following on from the dryer, wherein a flow distribution chamber is arranged between the pre-conditioner and the dryer and/or between the dryer and the sorption unit in order to minimize flow losses due to vortex formation and/or dead water zones. 
     
     
         15 . The system of  claim 2 , wherein the second functional unit has twice as many functional modules as the first functional unit.
